Hai hai everyone ,
so with the EEVEE rewrite underway (yay), i was thinking of opening a discussion to possible solutions to Alpha Blending’s sorting issue (if they even exist ? ), it seemed like the perfect opportune time to do so.
(For those who don’t know, this is a issue when transparency is turned on with “show backfaces” also turned on, you get these square artefacts with the Alpha Blend, picture borrowed from TimParaxade)
Since i know little on this problem in detail other than that it’s a sorting problem, i was wondering if anyone knows of a solution to this problem ?
I’m aware that Blender is not the only program with this problem, apparently all programs suffer from this error.
Material Settings — Blender Manual
T59803 [Shading] Backside obsures frontside when Alpha Blend is on (blender.org)
T62559 Eevee Alpha Blend Depth Error (blender.org)
My reason for this discussion is that although Alpha Hash gives a good solution, its has the issue of being very noisy with few samples which require denoising, which in the viewport is insanely distracting. So i was wondering if its possible to “Fix” Alpha Blend to give us a desired result without any noise.
Thank you for your time peeps
